We look at the division of 520604 by 4 
Our goal is to divide 520604 by 4.

Let's proceed to step 1:
5 divided by 4 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 4 from 5.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

Going ahead to step 2:
12 divided by 4 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Advancing to step 3:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtract 0 from 0 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 4

Going ahead to step 4:
4 goes into 6 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1301.0
Subtract 4 from 6 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Step 5:
When dividing 20 by 4, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13015.0
Subtract 20 from 20 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 4

Let's proceed to step 6:
The number 4 fits into 4 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 130151.0
If we subtract 4 from 4, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 130151.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 130151.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 130151.0 with a remainder of 0.0.
